Pro football fans typically celebrate the sport’s biggest game of the year with food, making it the second largest eating occasion of the year. This year, fans who choose Chipotle for their big game party can get just a little more to eat, for free. Simply purchase six or more “Burritos by the Box” on Sunday (Feb. 3) and Chipotle will give you a free burrito, bowl, salad or order of tacos when you bring back the receipt from your order to any Chipotle by Feb. 28.
